Asking yourself if heat is a factor in memory foam's ability to expand? It is, in fact!

Memory foam mattresses inflate more quickly when the room is warm, you move or roll about on the mattress, or you wait a few more days.

Part Of The Mattress Still Looks Smushed Or Compacted

You just got your brand-new memory foam mattress earlier this week. When you open the memory foam mattress, it doesn't inflate to its supposed shape. There is an issue with this.

There's a chance it won't appear as deep or won't cover the complete bed frame. There are various ways to break in a new mattress, but doing so may interfere with your sleep.

Tips And Tricks [Solution]

Loom and Leaf Mattress (has good corner expansion)

If you know how to make memory foam inflate & expand more quickly, you can get to sleep sooner. There are numerous ways to do this.

  • The mattress should be heated because memory foam is temperature-sensitive. It won't fully expand when it's cold out. To hasten the growth process, make sure your space is at least 68 degrees Fahrenheit (20 Celsius) warm.
  • Wait 72 hours - After removing the mattress from its packaging, you might want to leave it on the floor for a few days. This enables it to grow completely.
  • Move around on the mattress, as it can soften the surface of the memory foam. Frequently, 10 minutes of mattress movement will smooth things out.
  • After 72 hours, you should finally use your mattress for sleep. At first, there can be some discomfort. Your body ought to adapt gradually but steadily.
  • Obtain the ideal foundation - Your mattress may feel uncomfortable if the foundation is old. A new bed frame can be purchased at the same time as a new mattress!
  • Be patient – Most firms provide a sleep trial if you're not happy with a mattress. Giving it a fair shot is crucial; occasionally, finding the ideal mattress only requires a little patience.
  • Most importantly, get a good memory foam mattress. In our testing, we thoroughly tried the Loom and Leaf Mattress, and within our testing and the tons of user reviews, it proved to have exceptional corner expansion!
